[0035] Example

[0036] Please refer to Figure 1-2 As shown, this embodiment provides a lightweight and wear-resistant sole, comprising a midsole 1 and an outsole 2, wherein the midsole 1 is fitted on the outsole 2. An embedding channel 21 is provided on the outsole 2, and the embedding channel 21 extends along the thickness direction of the outsole 2; a mounting portion 11 extending downward is provided at the bottom of the midsole 1, and the mounting portion 11 is embedded in the embedding channel 21. The bottom surfaces of the outsole 2 and the mounting portion 11 are located on the same horizontal plane, and a plurality of anti-skid protrusions 3 arranged in sequence and at intervals are provided on the bottom surfaces of the outsole 2 and the mounting portion 11, and the anti-skid protrusions 3 include at least two fitting arms 31 extending outward.

[0037] Please refer to Figure 1 As shown, in this embodiment, the opening range of the embedded channel 21 covers the sole, arch and heel. The embedded channel 21 is provided on the outsole 2, and the mounting portion 11 at the bottom of the midsole 1 is embedded in the embedded channel 21 to form a combined sole, which effectively reduces the width of the outsole 2 at the corresponding position and reduces the resetting elastic force of the bending position in the middle of the sole, making the sole lighter during walking and bending. At the same time, the anti-skid protrusions 3 arranged on the bottom surface of the outsole 2 and the mounting portion 11 ensure that the sole has good anti-skid performance, and at least two outwardly extending fitting arms 31 are provided to increase the fitting area between the anti-skid protrusions 3 and the ground, thereby increasing the friction between the sole and the ground, and further improving the anti-skid performance of the sole.

[0038] A plurality of mutually spaced first limiting protrusions 211 are provided on the side wall of the embedded channel 21, and a first limiting groove 212 is formed between adjacent first limiting protrusions 211; a plurality of mutually spaced second limiting protrusions 111 are provided on the side wall of the mounting portion 11, and a second limiting groove 112 is formed between adjacent second limiting protrusions 111. The first limiting protrusion 211 and the second limiting protrusion 111 are respectively embedded in the second limiting groove 112 and the first limiting groove 212. The side wall of the embedded channel 21 fits with the side wall of the mounting portion 11, and a first limiting protrusion 211 and a second limiting protrusion 111 are respectively arranged at intervals. The two are respectively inserted in the interval space to form an engaging connection surface. The first limiting protrusion 211 and the second limiting protrusion 111 respectively provide limiting force to each other, thereby improving the connection strength between the mounting portion 11 and the limiting protrusion; increasing the fitting area between the mounting portion 11 and the embedded channel 21, enhancing the connection strength, and ensuring the stability of the connection between the midsole 1 and the outsole 2.

[0039] The free ends of the fitting arms 31 of the anti-slip protrusions 3 near the side walls of the embedded channel 21 and the side walls of the mounting portion 11 extend toward the first limiting protrusion 211 and the second limiting protrusion 111 respectively, making full use of the space between the first limiting protrusion 211 and the second limiting protrusion 111, making it easier to set up more anti-slip protrusions 3 and improving the anti-slip performance of the sole.

[0040] In this embodiment, the number of the fitting arms 31 of the anti-skid protrusion 3 is three, one end of the three fitting arms 31 is connected, and the other end of the three fitting arms 31 is a free end extending outward. The free end of the fitting arm 31 of the anti-skid protrusion 3 extends toward the connection position of the fitting arms 31 of the adjacent anti-skid protrusion 3. The three fitting arms 31 form a triangular star-shaped anti-skid protrusion 3, that is, the angle between the adjacent fitting arms 31 of the protective protrusion is 120°, and the three fitting arms 31 fit the ground from multiple directions, further improving the friction between the sole and the ground, and improving the anti-skid performance of the sole.

[0041] The sides of the adjacent fitting arms 31 of the anti-skid projection 3 are all provided with inclined surfaces 311, and the inclined surfaces 311 are inclined from the bottom surface of the anti-skid projection 3 outwardly toward the bottom surface of the outsole 2 and the mounting portion 11. The overall hardness of the anti-skid projection 3 is effectively reduced, and the elasticity of the sole is improved. Further, at least two inwardly recessed grooves 32 are provided on the bottom surface of the anti-skid projection 3, and the number of the grooves 32 is the same as the number of the fitting arms 31, and one end of the plurality of grooves 32 is interconnected, and the extension direction of the plurality of grooves 32 is the same as the extension direction of the fitting arms 31. In the present embodiment, the number of the grooves 32 is also three, and the three grooves 32 are distributed in a triangular star shape. The triangular star-shaped grooves 32 further reduce the overall hardness of the anti-skid projection 3 and improve the elasticity of the sole. At the same time, during walking, the anti-skid projection 3 is squeezed, and the groove 32 provides a pressurized space for the top of the anti-skid projection 3, and the top of the anti-skid projection 3 is squeezed toward the groove 32, which improves the contact time between the anti-skid projection 3 and the ground, thereby further improving the wear resistance of the sole. The number of the similar fitting arms 31 and the grooves 32 can also be two, four or more.

[0042] Please refer to Figure 1 As shown, in this embodiment, a notch 213 is provided on the side of the outsole 2 corresponding to the inner side of the sole, and the mounting portion 11 extends into the notch 213. Furthermore, the opening length of the notch 213 is less than the length of the mounting portion 11, so as to prevent the mounting portion 11 from being pushed down from the horizontal direction of the notch 213. In this embodiment, the extension direction of the connection line from the toe to the heel of the sole is the length. The notch 213 is located below the arch of the foot, so that the outsole 2 is a "C"-shaped outsole 2, and the middle connection position of the "C"-shaped outsole 2 corresponds to the outer position of the sole. When walking, the bending degree there is greater than that at the notch 213 position. The notch 213 is set at a position with a smaller bending degree, further reducing the width of the outsole 2 at the bending position, reducing the reset elastic force at the bending position of the middle part of the sole, and making the sole lighter during walking and bending. At the same time, the front free end of the "C"-shaped outsole 2 corresponds to the position of the sole behind the big toe, the middle connecting position corresponds to the position of the sole behind the little toe, and the mounting portion 11 corresponds to the middle position of the sole. The mounting portion 11 and the outsole 2 divide the force applied by the sole during walking, and use the anti-slip protrusion 3 with higher elasticity to unload the force, thereby reducing the wear of the outsole 2 and the mounting portion 11. Figure 1 In the figure, the thick lines are the side walls where the channel 21 is embedded.

[0043] Please refer to Figure 2 As shown, in this embodiment, the opening size of the notch 213 located on the top surface of the outsole 2 is larger than the opening size located on the bottom surface, so that the bottom opening of the notch 213 forms an inverted "eight" supporting structure, and the outsole 2 is located below to support the mounting portion 11 to prevent the mounting portion 11 from separating from the outsole 2 in the vertical direction, which would affect the integrity of the sole structure. Figure 2In the figure, the thick line is the side of the notch 213.

[0044] In this embodiment, the outsole 2 is provided with an upwardly extending blocking portion 22 at the toe position, and the height of the blocking portion 22 is greater than the height of the midsole 1. The blocking portion 22 increases the thickness of the toe position of the sole and protects the foot at the front end.

[0045] Please refer to the attached Figure 3 This embodiment also discloses a leisure shoe, comprising the above-mentioned lightweight and wear-resistant sole and an upper 4, wherein the upper 4 is fixed on the midsole 1.

[0046] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
